ARENA AND COMPANY, OF LOS ANGELES, CALIFORNIA, A CORPORATION OF CALIFORNIA BOX-LINER TUCKINO' ATTACHMENT FOR LIDDING MACHINES Application led March 27, 1929. Serial No. 350,423.

The present invention relates to crate lidding machines and more particularly to a tucking attachment for the paper lining used to cover the produce packed within their crate. l

One of the important objects of the invention is to provide a tucking attachment of this character adapted to engage the edges of the paper lining at the front and rear sides of the crate for tucking the same into position within the crate and simultaneously with the placing and securing of the lid thereupon. J,

A further important object is to provide adjustable means for the tuckingl attachment which enables its use upon a crate of various sizes. l

Another object is to provide an attachment of this character which may be secured in operative position upon a crate lidding machine of conventional structure without necessitating any changes or alterations in the construction thereof, which at the same time is of a simple and practical construction, efficient and reliable in performance,

compact in its arrangement, relatively inexpensive to manufacture and otherwise Well adapted for the purposes for which the same is intended. l

Other objects and advantages reside in the special construction, combination and arrangement of the various elements forming the invention as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof wherein like numerals refer to like parts throughout, and in. which Figure 1 is a fragmentary front elevational view of a lidding machine showing the tucking attachment in position with respect thereto.

Figure 2 is a perspective View of the forward tucking member.

Figures 3, 4 and 5 are perspective views of the rear tucking member and including the means for attaching the same in a stationary position to the lidding machine.

Figure 6 is a top plan view. Figure 7 is a fragmentary vertical sectional view through a crate illustrating the lidder and tucking attachment in position f or securing the lid and paper liner in position.

Figure 8 is a similar view showing the lidder and tucking attachment prior to engaging the crate lid.

Figure 9 is a vertical sectional view through a crate at the completion of the lidding and tucking operation.

Figures 1() and 11 are perspective views of the angle adjusting plate and the guide rod respectively for regulating the extent of inward movement of the forward tucking member,y and Figures 12 and 13 are perspective views of the forward tucking member.

Referring now to the drawings wherein for the purpose of illustration I have disclosed the present invention in operative position upon a lidding machine of conventional construction, the numeral 5 designates the rear frame member of said lidding machine and with which is associated a back guard 6 and base 7 for supporting a crate of produce 8 in position upon the machine. The lidding machine also includes a lid press 9 which is carried upon the frame for vertical movement and operated in a manner well known in the art for pressing the lid 10 downwardly upon the top of the crate in order that the, lid may be nailed to the crate.

In packing fresh vegetables, fruits and other produce for shipment, the crate is usually provided with a paper liner indicated at 11 and space is provlded at the top of the crate for packing a quantity of cracked ice 12 therein to preserve the contents of the crate and over the ice is placed a liner cover 13. During the lidding operation the edges of liner 13 becomes puckered through the depressing action of the lidder in placing the lid inposition and such puckering of the liner not only presents an unattractive appearance but also results in the edges of the liner becoming torn so that the cracked ice will spill therefrom and .dirt will be permitted to enter the crate. The present invention accordingly is intended to provide means for tucking the front and rear edges of the cover or liner inwardly of the crate andto form a packing means for the cracked ice so as to prevent the bulging of the same at the front and rear edges of the crate during the lidding operation.

In carrying out the invention I provide a front tucking member 14 which comprises a horizontally disposed rigid strip of metal or the like secured to a T-head 15 formed at the outer end of a bar 16. The inner end of the bar is disposed in overlapping relation with a similar bar section 17, the overlapping en-ds of said bar sections being provided with openings 18 through which bolts 19 may be inserted for securing the sections in longitudinally adjusted position with respect to each other. The sections of the bars are'slidably mounted upon the top of the lidder. 9 by brackets 20. The inner end of the bar section 17 is forked as shown at 21 and is pro* vided with a pair of spaced rollers 22.

Between the rollers 22 an upwardly extending rod 23 is inserted, said rad having its lower end formed into an eye 24 and through which a threaded rod 25 is freely inserted. The rod 25 extends rearwardly of the machine with one end threadedly engaged to an upper horizontally disposed back guard 26 secured to the frame 5 of the machine and which back guardA constitutes a support for attaching the rear tucking member 27. The back guard 26 and the rear tucking member 27 are provided with registering openings 28 and 29, respectively, through which bolts 30 \may be inserted for securing the tucking member in vertically adjusted position in order that the same may be adjusted to crates of various heights and so that the rear tucking member may rest upon the upper edge of the rear of the crate and flush with the inner wall thereof, as clearly illustrated in Figures 7, 8 and 9 o f the drawings. 1

The outer ends of the back guard 26 are offset, in a plane forwardly of the guard, as shown at 31 to form abutment for the ends of the rear tucker member 27.

The upper en-d of the rod 23 is inserted through an opening 33 formed in the forward end of a plate 34 adapted to be secured to the upper portion of the frame of the machine 5 in forwardly or rearwardly adjusted position by means of a row or openings 35 formed at the rear of the plate through which an attaching-bolt 36 is inserted. The plates 34 provides a means for adjusting the upper end of the rod 23 forwardly or rearwardly with respect to the machine and the lower end. of the rod 23 may also be forwardly or rearwardly adjusted by means of a pair of jam nuts 37 threadedon the bar 25 in spaced relation forwardly and rearwardly of the lower en-d of the bar 23. A washer 38 is also carried on the threaded bar 25 and interposed between the forward nut and the rod 23. It will thus be apparent that the bar 23 may be inclined forwardly and upwardly from a vertical plane, as clearly illustrated in Figures 7 to 9, inclusive of the drawings, whereby during the -downward movement of the lid 9 the forward tucking member 14 will be drawn rearwardly. Accordingly, as the forward tucking member engages the forward edge of the liner 13 the same will be forced downwardly and inwardly of the front side of the crate. By reason of this action the front edge of the liner will be tucked inside of the frontl side of the crate during the lidding operation.

The manner in which'this tucking actionA is accomplished is more clearly illustrated in Figures 7 and 8 of the drawings. v

It is obvious that my invention is suscepti-y ble to various changes and modifications in` out of engagement with one edge of the cratel liner whereby to force the liner inwardly of the crate. 4
